Hearing device and method for operating a hearing device

Abstract: It is suggested to use a time-averaged activity parameter set. An improved adaptation of the hearing device to a current acoustic environment can be achieved. adjusting the respective sub-function by means of said activity parameter set. deriving from N predetermined base parameter sets assigned to the respective sub-function and in dependence of said class similarity factors an activity parameter set for the respective sub-function, wherein each of said N base parameter sets assigned to the respective sub-function is assigned to a different class of said N classes; deriving, on the basis of said input audio signals and for each class of N classes each of which describes a predetermined acoustic environment, a class similarity factor indicative of the similarity of said current acoustic environment with the predetermined acoustic environment described by the respective class, wherein N is an integer with N≧2; for each of said M sub-functions: deriving said input audio signals from a current acoustic environment; and The method for operating a hearing device having an adjustable transfer function comprising M sub-functions, wherein M is an integer with M≧1, and wherein said transfer function describes how input audio signals generated by an input transducer unit of said hearing device relate to output audio signals to be fed to an output transducer unit of said hearing device, comprises the steps of: (end of abstract)
